Application filed January 6. 1920. Serial No. 349,720.

To all whom it may concern.-

Be' it known that T, WILLIMAN H. Brno, a

citizen of the United States of America, and resident of Sour Lake, in the county of the saidinvention has for its object the provision of novel means for supplying steam to the fluid so that oxygen suficient to support combustion will not m n, the flame, the said invention having for its object furthermore the provision of novel means for installing the apparatus in a receptacle or tank and providing means whereby the steam may be delivered to the fluid in the tank so that the steam will pass through the fluid whereas other steam will be torced downwardly on the flame and on to'the surface of the burning fluid.

With the foregoing and other objects .in

view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

in describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts .in. the several views, and in whichk Figure 1 illustrates a plan view of the apparatus embodying the invention, the receptacle being shown in section; and

Fig. 2 illustrates a vertical sectional view of a .receptacle' with the device applied thereto. i

In these drawings 5 denotes a receptacle such as a tank of the storage type for holding oil and 6 denotes a curved piping which surrounds the tank at the bottom. The pipe 6 might be termed a header in that it has suitable source. 7

At a predeterminedlocation and preferably "at each 90 of the circle risers 8 are tapped into the header-and these risers ex-v a steam supply pipe 7 leading to it from any tend to nearly the top of the tank. The

upper ends of the r isers have couplings 9 of appropriate typeto which horizontally disposed oints 1O are connected, the said joiints Specification of Letters Patent.

being in communication with a sprinkler or spraying ring 11 supported within the tank by the brackets 12. The sprinkler ring 11 is formed in sections and each section has its ends joined to tour-way couplings 13, it.

being understood that the joints 10 lead into one branch of each of said couplings. Horizontally disposed sprinkler pipes it are connected to other branches, of the couplings and the said pipes 14are connected tobranches 15 ot a spider 16 which occupies the center of the tank near the top, the said spider having a downwardly extending sprinkler pipe 17 connected "to it, the said plpe 17 terminating near the bottom of the tank and having radial sprinkler branches lid which rest on the bottom of the tank to aid in supporting the structure and for the delivery of steam at the bottom of the tank.

Each coupling 9 has a valve stem 19 rising from the valve plug .ZOrOtatable in the coupling and by this means, the circulation of steam may be controlled although in most instances it will not be necessary to interpose a valve in the coupling 9 for the reason that each riser has a valve 21 near the bot tom which may be manuall" operated to permit the circulation of fluid l The arms of the spider-have the pipes 14 connected to them by means of the threaded couplings 22 and the joints 10 may comprise a nipple 10 threaded in the coupling 10 which coupling 10 is in communication with the tour way coupling 13 but these latter features are details of construction which may "be varied to suit particular requirements although the device as shown embodies the preterred construction as far as it has been developed. v

The apertures of the ring and sprinkler tubes at thetop of the tank should open downwardly or those in the ring might open diagonally inwardly, and the sizes of these V apertures and their exact location may be varied .to suit particular requirements and the same is true with respect to the proportions or sizes of the ring pipes, risers and radially extending pipes connected to the risers and extending crosswise of thetank near the top, a hollow spider to which the pipes are connected, the said pipes having perforations therein, a sprinkler ring-connectedto the pipes within the tank, a vertically disposed perforated pipe connected to the center of the spider and radiating sprinkler pipes connected to the bottom of the vertically disposed perforated pipe.

2. In a fire extinguishing apparatus, a sprinkler ring within a tank, means for sup porting the ring therein, means for supplyare connected, a vertically disposed perforated pipe connected to the spider, and radially disposed sprinkler arms at the bottom of the tank connected to the said vertically disposed perforated pipe.
